When trying to diagnose PMR I was seeing an orthopedic Dr. My shoulders were particularly sore but my legs and hands were not far behind. He ordered an MRI of my shoulders. I had almost the exact same results. First one is a slap tear. Which according to him anyone over 70 will probably have. Then tendonitis and bursitis. Just swelling in the tendon attachments and inflammation in the joints. Probably a little arthritis. So he sent me off and said not that bad. I just needed to fix the inflammation and recommended a rheumatologist. I have been off steroids for 2 years now. He apparently was right. I still lift weights every day and exercise. No pain now that the inflammation is gone. But I do agree . I think we all have some underlying conditions that become more pronounced with PMR and age.
